IMPRQVEMENT IN WELL-BORING APPARATUS.

The Schedule referred to in these Letters Patent and making part of the name To all whom it may concern.-

Be it known that I, NOAH H. LINDDEY, of Bridgeport, in the county of Fairlield'and State of Connecticut, have invented. a new and useful Improvement in Welhboring Apparatus; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being bad to theaccompanying. drawing ibrming part of this specification.

Figure 1 is a detail sectional yiew of my improved apparatus.

Figure2 is a top view of the guide and brace for the coupled shaft.

Figure 3 is a side view of the boring-tool for enlarging the well-bore below the curbing, part being broken away toshow the construction.

Figure 4 is a detail sectional view of the same, taken through the line xzqfig. 3.

. Figure 5 is a detail sideview of one forniof tool for supporting the dirt in the boring-tool while being raised from the well.

Similar letters of reference indicate corresponding parts.

My invention has for its ohject to furnish an improved apparatus for boring or digging wells, which shall besimple in construction and effective in operation, cutting out and raising the dirt with dispatch, while, at the same time, leaving the inner snrihce of the bore or cut straight and smooth; and a It consists in the construction and combination of the various parts of the apparatus as hereinafter more fully described. 1

A represents a ti'arncwo k erect-ed ovcr the .place where the well to be dug, to support the operating mechanism.

B is the shaft or'rod by means of which the digging- ;tools are operated, and which is made in sections of convenient length.

The sections have a tcnon formed upon one end and a socket in the other, for convenience in coupling them together, and are held in place, when coupled, by transverse pins, as shown in fig. I1.

The shaft B has a rack formed upon two of its opposite sides to receive the teeth of thetwo gearivhecls Q, which are attached to the two shafts l).

The two shafts I) cross the frame A upon the op posite sides of 'the shaft or bar B, and revolve in bearings attached to said frame in such a way that the shafts I) may be moved longitudinally to throw the said wheels C out of and into gear with the shaft -B when desired. The shaft 15, when out of gear with the gear-wheels O, is revolved to force the boring. or digging-tool into the ground by a sweep E, attached to the npperi end ofthe upper length or section of the shaft B, as shown infig. l.

The shafts D are revolved, to .rai'se and lower the jointed shaft B and its attachments, by means of cranks, 1*,attached to their ends, as shown in fig. 1.

- G is the boring or digging-tooh'which is made open at its lower end, and to its upper ond is attached, or ,nporrit is formed, a shank, g, which 'is conncctedto .the lower end of the lowest length or section of the shaft B, in the same manner as the: sectionsot said shaft are connected with each. other.

The connection between the shank g and the body one or more rings or flanges, g?, to increase the friction between said inner surfaces and. the contents of the said cylinder, to assist in rctainingsaid contents in place while being raised out of the well. 4 To the lower end of the shank g of the borer G is secured the upper end of the boring tool H, by means of a touch, socket, and pin, to support the middle part of the contents of said'cylimlcr while being raised from the well.

The tool llf maybe made with a spiral groove, twist, or thread, as shown in fig. 1, or with an enlarged head or lower end, as shown in fig. 5, or in any other suitable form, the form being immaterial so long as it is such as to oifcr some slight support to the middlc. part of 'the contents of the said cylinder. In some soils the central tool H will notbe required.

\Vhontho entire length of the tool G has passed intov the ground, and it is desired. to raise it with its contents, the earth is packed therein bya blow on the shaft ll, by the gearing, or bv compression applied in any other manner.

The joints of the shaft B are strengthened, and the said shaft kept in avert-ical position and in the center of the well, by the guard I.

The guard I formed by attaching the edges of a metal place, i", to the edges of two circular ends 01' heads 1''.

The edges oi" the plate i are deeply notched, as shown in iig. 1, so that by contracting the said edges slightly the middle part of thcplatcmay he made to bulge, as shown in iig. l.

The guard l is made in two parts, as shown in fig. 2, which parts are hinged to each other at one edge, and dctachabl y secured at the ot her ed go by a hasp and rod, or in any oihcr convenient detachable manner.

By this construction, as the shaft- B, descends Into the swell the guard I is carried down witlnit, and the bulging 'middle part of its sides rest against the inner snrface of the cut and thus keeps the said shaft in a vertical posit-ion. The bulging sides of the guard I, coming in contact with the surface of the out, tends to smooth said surface rather than dig it out, as a guard of an0ther,t'orm would do.

In digging through water, or through strata that cannot be raised by the tool G, the tool J is used, the body of which is cylindricalin form, andhas two'or more cutters orpoints, 'j, projecting from its lower edge, which separate the soil to be raised from the wall of the well.

The bottom j of the tool J is made in two parts, semicircular in their general form, and set at an inclination with each other, as shown in fig. 4.

The half of each straight edge upon the opposite side ofthe central shaft of the tool J projects beyond the other part, and is serrated, to enable it to take a better hold upon the ground. The other edges are turned up slightly and have flaps hinged to them, as shown in figs. 3 and 4, so that when the tool is raised the said flaps may close down and prevent the material in said tool from escaping.

The straight edges of the parts of the bottom of the tool J are supported by a rod passing through the lower part of the shaft or stem of the said tool, and its curved edges are supported by strips or flanges attached to or formed upon the inner surface of the lower pal-tot the cylindrical case of said tool.

K is a brace or hail, the ends of which are secured to the upper part of the cylindrical case of the tool J, and through a. hole in the middle part of which the shaft or stem of the said tool passes.

L is another bail, through a hole in the middle of which the said shaft passes.

.the cylinder.

The ends of the bail L are slot-ted to receive a crossrod attached to the upper part of the case or cylinder of the tool J, as shown in figs. 3 and 4. The bail L is curved, as shown in fig. 3, so as to project beyond The bail L is designed for use to excavate the sides of the well beneath the lower end of the curbing, so that the said curbing may be forced down as the digging progresses.

The dirt dug out by the bail L falls into the cylinder of the tool J at the same time that the said cvlinder is receiving dirt from its lower'end.

\Vhen the tool J is drawn up the bail Kis forced inward by the lower edge of the curbing, and the tool passes up freely.

Having thus described my invention,

claim as new and desire to secure by Letters Patent- 1. The boring-tool G, made in the form of a hollow cylinder open at its lower end, having its upper end perforated, its lower edge serrated, and having one or more circular ribs or flanges attached to or formed upon its inner surface, substantially as herein shown and described,,and for the purpose set forth.

2. The combination of the elastic projecting and self-adjusting bail L, with the cylindrical borh1g-tool J, provided with a bottom and boring-lips, substantially as herein shown and described, and 'for the purpose set forth.
